Patent GB-1180703-A (GB)
Title: Coil Forming Apparatus and Process
Inventor: NORMAN HARRY HERSHEY
IPC: B21F3/04
Filed: 1968-06-10
Abstract: 1,180,703. Making springs; coiling; twisting. H. H. NORMAN and S. BALISKI. 10 June, 1968 [21 Aug., 1967], No. 27403/68. Headings B3A and B3E. A method of forming a spring from a wire comprises first uniformly circumferentially stressing the wire and secondly controlling the shape assumed by the stressed wire. Apparatus for carrying out the method is in the form of a dual machine for winding clockwise and anticlockwise springs and each includes a vertical straightener 27, horizontal straightener 28, electrically driven feed rollers 32, 33 for pulling the wire 18 off a spool 24 and coiling the wire into three or four loops within a housing 36 wherein a sensing arm 40 controls the speed of the feed rollers so that the wire is fed at a constant rate to a spring forming mechanism 50. From the housing 36 the wire passes through table 22 via shoot 45 and is lapped around a grooved wheel 46 and through a guide 18 to the mechanism 50 supported on the table 22. The mechanism 50 comprises an upper and lower platen 52, 53 respectively and an oil tray 54 which rotate in unison with respect to a base 51 under power supplied by motor 60 via belt and sprocket gearing. A tubular shaft 55 is suspended from the platen 53 and receives the wire guide 18 so that rotation of the platen shaft and guide imparts a longitudinal twist to the wire. Extending upwardly from the platen 52 is a stanchion 59 about which the spring is guided and which is geared to remain stationary with respect to the base 51 despite rotation of the platen 52. Also extending from the top of platen 52 are a feed wheel 57 and a bias wheel 58 embraced by a band 145 the feed wheel rotation being generated by the rotation of platen 52 in a planetary gear system whose ratio can be adjusted to alter the number of revolutions of the platen 52 for each revolution of the feed wheel 57. The wire from the guide 18 passes through the lower and upper platens 53, 52 via oil proof couplings and is directed into a groove 140 in the feed wheel 57 where it is trapped by the band 145. A scraper 146 keeps the band clean and scrapers 148, 149 keep the grooves in the feed wheel free from dirt. As it passes from the feed wheel 57 the wire tends by itself to form into a coil or spring around the stanchion 59 the diameter of the coil being restrained by adjustable guide rollers 161, 162 and 163 (Fig. 8). Rollers 167 and 168 act as pitch controllers. Coil rotational sensing plates 175 co-operating with an electronic sensor 180 control the planet gearing to correct for any undesired rotation of the spring as it is being formed. In a modification the mechanism 50 may include means for winding springs having variations in pitch and/or diameter (Fig. 15). Such means include a cam 208 (Fig. 12) mounted on the shaft of the feed wheel 57 said cam through lever mechanism adjusting the position of the control roller 163<SP>1</SP> mounted on a rocker arm 202. The pitch control roller 168<SP>1</SP> is similarly controlled from a cylindrical cam 220 on the feed wheel 57.

Filed: 1973-06-11
Abstract: 1426928 Mixing apparatus C H HEISE 11 June 1973 [10 June 19721 27586/73 Heading B1C [Also in Divisions C3, E1 and F4] In a method and apparatus for preparing a road surfacing composition, a plurality of batches of various grain size ranges of aggregate are separately metered, dried, heated and separated into a course fraction, a sand fraction and a "self-filler" fraction; each sand fraction is then returned to the course fraction from which it was separated, the self-filler fractions are combined, and the coarse and sand fractions are then mixed together with the mixer self-filler fraction and a binding agent. As shown in Fig. 1 six batches of aggregate 1 of diverse grain size ranges are each associated with a metering, drying, heating and classifying unit 2 having a classifier 7. Coarse and sand fractions are discharged to a conveyer 5 and thence to a bin 6, and self-filler fractions to a hopper 9, weigher 11 and bin 12, optionally with additional filler 10. Coarse aggregate, filler and bitumen (from a supply 13) are then mixed at 14. The metering, drying, heating and classifying unit 2, Fig. 2, comprises a hopper 16 delivering via a metering screw 17 and hollow feed screw 19 to the interior of a rotatable drying drum heated by a burner 24. Fines are entrained at 33 by the current of heating gas and conveyed through the hollow screw 19 and duct 29 to a first separating stage 22 where sand is precipitated at 35 on to the outer surface of the drum 18 which is provided with a conveying screw 25. Course aggregate and sand are thus delivered to an elevator 20 in the buckets of which they are mixed, and discharged to a hopper 3. The self-filler fraction which has been separated from the sand at 36 is precipitated by the second classifying stage 23 into a screw conveyer 27 which combines all the self-filler fractions and delivers them to the hopper 9, Fig. 1.

Title: Automatic fouling protection search circuits for railway signalling installations
IPC: B61L25/06
Filed: 1958-08-29
Abstract: 891,593. Route setting; fouling protection. STANDARD TELEPHONES & CABLES Ltd. Aug. 29, 1958 [Sept. 4, 1957], No. 27793/58. Class 105. In a fouling protection arrangement in which a set of points W1, Fig. 1, forming part of a route between tracks 1 and 2, requires fouling protection from the direction of points W2, a fouling protection search signal arriving at the facing end of points W2 from points W1 is transferred by relay circuitry in the direction of the trailing ends of the points whereby protection is obtained from points W3 and signal S. In the relay group of points W1 a contact FlS 11  Fig. 3, is reversed when the route is set up and changes the potential on a fouling protection search lead connected to a relay group associated with points W2. Relay FlS2 which is normally energized via its holding winding 5, 6 and resistor Wi22 is now released by current flow in its counter excitation winding 1, 2 via contacts FlS11, FV21, FlS24 and contacts FlU+21 and FlU-21 of two fouling protection proving relays in their normal positions. The release of relay FlS2 reverses the potential, at contacts FlS21 and FlS22, on the search leads connected to relay groups associated with points W3 and signal S. If the points W3 are not in a position to provide protection, points setting relay WS3 is energized via points position relay contact WL32 and contact FS31. When the points are correctly positioned, points position relay contacts WL32 and WL31 assume the position shown breaking the circuit to the setting relay and releasing relay WV3. Via circuits (not shown) the release of relay WV3 ensures the locking of the points W3. On reversal of potential by contact FlS22 on the search lead to the signal relay group S, relay SV is released and locks signal S at danger.

Abstract: 428,581. Valve generating circuits. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Electra House, Victoria Embankment, London.-(Assignees of Finch, J. L. ; Patchogue, Long Island, New York, U.S.A.) Oct. 1, 1934, No. 28076. Convention date, Oct. 19, 1933. [Class 40 (v)] A crystal - controlled valve oscillator is arranged to generate an harmonic of the crystal frequency by including the crystal 16 in series in the feed-back connection 30 from the plate coil 14 to the tuned grid circuit 38 which latter is tuned to the desired harmonic. The plate coil tapping 32 is at a point of low oscillatory potential, and the grid coil tapping 36 is also at a point of low oscillatory potential opposite to that of the grid, on account of the intermediate connection to the cathode. The crystal electrode-capacity is balanced by the capacity 15. The screen-grid is kept at earth potential by a condenser 12, which may with the inductance of the screen-grid lead constitute an acceptor circuit for the desired harmonic. The plate tapping may be at a point beyond the cathode connection of the coil 14, and the grid tapping at a point on the grid side of the coil 38 (Fig. 2 not shown). The grid coil tapping may be omitted and the lead 30 may include a coil inductively coupled to the coil 38, an electrostatic screen being interposed (Fig. 3 not shown).

Abstract: 1400019 Electromagnetic fuel injectors SOC FINANCIERE ET INDUSTRIELLE DES ATELIERS ET CHANTIERS DE BRETAGNE 15 June 1972 [1 July 1971] 28108/72 Heading FIB The unsticking of the stationary and moving armatures of an electromagnet core of a fuel injector after an energizing signal flows through a main winding on the core includes the application of a second signal to an auxiliary winding on the core to produce a magnetic field oppositely directed to the magnetic field produced by the energizing signal thereby cancelling the magnetic field of the main winding. The main electromagnet winding 3, Fig.1, is energized from a signal generator 5 which transmits signals to a computer 7 which determines, in accordance with engine operating variables the transmission of square or rectangular waves which are amplified by amplifier 9 which outputs distorted control signals 10, Fig. 1A. The leading edge of the square signal 8, is detected and supplied to a shunt device 11 which outputs a signal 12 to a monostable 13 which outputs a square signal 14, whose leading edge 14L coincides with the trailing edge 8T of signal 8, to an amplifier 15 which outputs a distorted signal 16. The latter flows through an auxiliary winding 4 to cancel the resulting field. In a modification a further monostable (17), Fig.2 (not shown), precedes the monostable 13 so that the action of the opposing signal on the axillary winding 4 can be shifted.

Title: Improvements in trip mechanisms
Inventor: JACKS ERIC
IPC: F42C7/02
Filed: 1968-06-13
Abstract: 1275254 Spring-operated trip mechanisms ENGLISH ELECTRIC CO Ltd 13 June 1969 [13 June 1968] 28224/68 Heading F2S [Also in Division H1] A spring-operated trip mechanism comprises a plunger 6, spring 11, latch 18 and delay means 25 and operates as follows. When the plunger is depressed against the spring bias, the latch engages a pin 13 on the plunger to retain the latter, the latch taking up the broken line position. In its movement from the full line to the broken line position, the latch sets the delay means in operation. The effect of this is to return the latch towards its initial position and, after the required delay, the latch disengages from the pin and the plunger returns rapidly to its initial position. The delay means may take the form of a rack-and-pinion equipped with an escapement which, when biased by the spring 11, constitutes a linear spring motor. The spring 21 attached to the latch itself makes the latter act as a toggle, i.e. it moves rapidly once a deadcentre position has been passed. The housing 1 is such that the apparatus as a whole is of the same external form as a fuselink cartridge of the kind which emits a striker pin. The present apparatus is designed for insertion in a switching installation in place of such a fuselink, as a means for testing the installation's response to fuse action.
